This invention provides a direct methanol fuel battery, which does not hinder the smooth current utilization in the compact district of high current, and is able to fully guarantee the battery output and guarantee the stability of long time by using as the fuel battery. The direct methanol fuel battery in this invention includes: a first fuel adjusting layer (40), a second fuel adjusting layer (50) and a third fuel adjusting layer (60) which are mounted between an anode catalyzing layer (20) and an anode GDL layer (70). The third fuel adjusting layer (60) has a stoma which is less than the second fuel adjusting layer (50); and the first fuel adjusting layer (40) has a stoma which is less than the second fuel adjusting layer (50) and has a stoma which is bigger than the third fuel adjusting layer (60).
